Background
- Grossly visible blood in the anterior chamber of the eye
- Typically caused by blunt trauma to the orbit
- Can result in permanent vision loss
- Outcome dependent on prevention of rebleeding and control of intraocular pressure
- In non-traumatic hyphema, all black patients should be screened for sickle cell disease with hemoglobin electrophoresis
Clinical Features
- Vision loss
- Earliest symptom is decreased vision
- Eye pain
- History of trauma to eye
- Direct and consensual photophobia
- Nausea and Vomiting
- Hyphema grading correlates to IOP increase[1]
- Grade 0 to IV
- 13.5% have IOP increase in Grade I to II
- 52% with IOP increase in Grade IV
Differential Diagnosis

^Emergent diagnoses ^^Critical diagnoses
Spontaneous hyphema (non-traumatic hyphema)
- Sickle cell disease
- Ocular or laser surgery
- HSV, VZV uveitis
- Neoplastic
Evaluation
evaluation is best performed under slit-lamp exam
- Blood in anterior chamber
- May only see difference in color of irises if patient is supine because blood layering is gravity dependent
- Blood in anterior chamber only visible on slit lamp is a microhyphema
- Vision loss / Acuity changes
- Inspect the lids, lashes, lacrimal ducts, and cornea
- Corneal abrasions often co-exist
- Assess direct and consensual pupillary response for the presence of a relative afferent pupillary defect
- Assess for Ruptured Globe which is associated with high energy mechanisms (shrapnel, BB guns, paint balls, etc)
- Check intraocular pressure after Globe Rupture is excluded
- Inquire about bleeding diathesis, anticoagulant/NSAID/aspirin use
Management
- Elevate head of bed and upright position to layer blood by gravity, open visual field while blood resorbs
- Eye shield
- Pharmacologic control of pain and emesis
- Weigh risks and benefits of stopping NSAIDs, ASA, anticoagulants
- Consult ophtho regarding:
- Dilation of pupil to avoid "pupillary play"
- Constriction and dilation movements of the iris in response to changing lighting
- Can stretch the involved iris vessel causing additional bleeding
- Use of topical alpha-agonists and/or acetazolamide to decrease intraocular pressure
- Dilation of pupil to avoid "pupillary play"
- No reading (accommodation may further stress injured blood vessels)
- Cycloplegic
- For comfort if globe rupture has been excluded
- Topical steroid
- Treat any underlying coagulopathy
- If IOP elevated:
- Timolol
- Topical alpha-adrenergic agonist
- Carbonic anhydrase inhibitors
Disposition
- Should be made by the ophthalmologist after examining the patient
- Hyphemas <33% of anterior chamber are frequently managed as outpatients
- Patients being managed as an outpatient should have ophthalmologist referral and consider outpatient screening for spontaneous hypthemas due to the association with sickle cell disease and hemophilia
Prognosis
- Rebleeding worsens prognosis as patients are at higher risk of permanent vision loss.
- Occurs 3-5 days after initial incident
- Complicates ~30% of cases
- Populations at highest risk:
- Sickle Cell disease or sickle cell trait
- Bleeding dyscrasia (including aspirin, NSAID, or anticoagulant use)
- Initial intraocular pressure >22 mmHg
- Pediatric patients
Grade | Anterior Chamber Filling | Normal Vision Prognosis |
I | <33% | 90% |
II | 33-50% | 70% |
III | >50% | 50% |
IV | 100% | 50% |
